Done that. The wire bail is generally more than sufficient to protect the cork from ejecting, and the bottle is usually more than durable enough as well. But I do recommend good padding, particularly for the flutes.
It is possible TSA may want to look further (inspect bag contents) - Champagne bottles in particular have been implicated in security-related problems in the past, and they may remember that. I'd recommend packing well and a TSA-approved lock.
¡Felicidades! to the happy couple.
